I've been waiting years for them to conduct this experiment. It's actually a side show using spare antiprotons which are a by product of ther mega big bang collision work. However nobody has actually ever gravitational weighed antimatter. They have observed its inertial mass but most folks assume it behaves the same as matter gravitationally with some exotic gravity theories of minor variations. However there has been this long standing hypothesis that antimatter is matter under time reversal. Some evidence violation of time reversal symmetry has been seen in even more exotic particle but all under earths gravitational field. But mostly it behaves like matter flowing backwards. Grandfather paradox violation would be isolated in the two forms as antimatter and matter annihilate when contacted, but photon or quantum information could be transferred outside of time spontaneously.

This has lead me to invent the temporal telegraph. A devise that once created would send a message back to itself in time. (A temporal telephone or Internet is also possible but would require extremely more bandwidth to be practical considering the minute amounts of antimatter avaiable.) Antihelium three would be best and only a couple nuclei of this gets made and nobody has made neutral helium three. Indeed anti hydrogen atoms last no more than one tenth of a second in this recent octopol trap. But a reverse time magnetic bubble memory could be someday built. Only problem I have not solve is how to get an open line from all the calls further from the future streaming in but folks trying to reach their bookies or stockbrokers.

Dear Maryanimal:Yes, your keyboard is the most likely source of the trouble. Two possibilities: Either a Hoggs Bison stepped on the keyboard, or there is a God Particle stuck in the enter key. Either way, you should now enjoy a root beer float, and then buy a copy of the Dan Brown book where CERN almost blows up the Vatican. Oh... And... Bartender, no more for the old coot with the furry face.
